Description
Technical field
The utility model relates to builing industry, belongs to the steel column foot of steel work single storey industry workshop especially.
Background technology
At present, single storey industry workshop adopts steel work more, and steel column foot is pressed post and basic power transmission characteristics, can be divided into hinged column base and rigidly connect suspension column.To the steel-structure factory building of traversing crane is set, general adopt of steel column rigidly connects suspension column more, to improve the horizontal lateral deformation stiffness of factory building.Rigidly connect the usually crab-bolt formulas that adopt of suspension column more, as depicted in figs. 1 and 2, comprise anchor bolt 1, base plate 2 ', stiffening rib 3 ' and steel column 4, pea gravel concreten or high-strength grout 8, basis 9 ', for guaranteeing the anti-bending bearing capacity and the rigidity of base plate, base plate 2 ' thickness generally should be less than 20mm, and should not cause base plate thickness bigger like this less than the steel column edge of a wing 6 thickness.Anchor bolt 1 is arranged on 6 outsides, the steel column edge of a wing, and its diameter is not less than 24mm.Lifting for ease of steel column 4, the crab-bolt aperture should be than the big 20mm of anchoring crab-bolt 1 diameter, also to reserve the structure distance of anchoring anchor hole, thereby cause base plate 2 ' planar dimension bigger, finally cause base plate 2 ' steel using amount excessive to the steel column edge of a wing 6 and base plate 2 ' edge.Be to strengthen the rigidity and the bearing capacity of suspension column, be provided with a fairly large number of stiffening rib 3 ', cause that the suspension column steel using amount increases.The diameter of anchoring crab-bolt 4 and quantity are determined by calculating, but Shang Yin meets the structure requirement, and its diameter is not less than 24mm.In addition, because of base plate 2 perforates bigger, crab-bolt nut lower bolster 7 should be set, its thickness is not less than 20mm by the structure requirement, backing plate 7 length of sides are 3 (d+2) mm, and the diameter of anchoring crab-bolt 4 is d, for guarantee 4 pairs of base plates 2 of crab-bolt ' reliable constraint, the employing double nut is fastening, and crab-bolt system steel using amount is bigger like this.Be to guarantee the bearing capacity of suspension column, the post edge of a wing 6 and base plate 2 ' should adopt the butt weld of full penetration groove to be connected, welding requirements is higher, and workload is bigger.In addition, more because of stiffening rib 3 ' quantity, cause the making of plate and welding job amount bigger.
In a word, process crab-bolt formula rigidly connects the long-term use of suspension column, and find to there is a lot of problem and shortage: its main problem is that base plate thickness is bigger, and base plate, suspension column and crab-bolt system steel using amount are excessive.The plate complex structure, the workload of making and welding is heavy.
The utility model content
The technical problems to be solved in the utility model provides a kind of steel column plug-in type and rigidly connects suspension column, and this rigidly connects suspension column can save a large amount of steel effectively, can avoid the complexity of member to make, and reduces the welding job amount.
For solving the problems of the technologies described above, a kind of steel column plug-in type of the present utility model rigidly connects suspension column, comprises steel column, basic rim of a cup, and described basic rim of a cup is the shape of falling a truncated rectangular pyramids rim of a cup.
Preferably, fix by pouring nothing contraction pea gravel concreten or high-strength grout between described steel column and the basic rim of a cup.
Preferably, described steel column bottom is provided with a base plate.
Preferably, be positioned at basic rim of a cup top above the described steel column and be provided with the web stiffening rib.
Preferably, described web stiffening rib is 70～120mm apart from the distance of basic rim of a cup end face.
Preferably, the distance of the described steel column edge of a wing and basic rim of a cup side is 30～100mm.
Preferably, the distance of base plate on the described steel column and basic rim of a cup bottom surface is 30～70mm.
Preferably, the degree of depth that described steel column inserts rim of a cup is not less than 1.5h, and wherein h is the steel column depth of section.
Preferably, the degree of depth of described steel column insertion rim of a cup is not less than 1/20 of steel column length.
The utility model makes to cause compared with prior art owing to adopt technique scheme, and advantage and good effect that it has are:
The steel column bottom is provided with base plate, and when steel column lifted, the pea gravel concreten or the high-strength grout that help under the base plate better supported steel column, are convenient to the adjustment and the correction of steel column.In addition, base plate is set also helps steel column to the more uniform transmission pressure in basis, avoid stress too concentrated, base plate thickness requires thinner, and steel using amount is less.
More than the end face of steel column basis the web stiffening rib is set, under the local stable prerequisite that guarantees web, for pouring and vibrate pea gravel concreten or high-strength grout provide the operating space, help the abundant and vibration compacting of pea gravel concreten or high-strength grout pouring, the stiffening rib thickness requirement is thinner, and steel using amount is little.
It is few that plug-in type rigidly connects the suspension column plate, makes simply, and the welding job amount is little, and welding requirements is low, and steel using amount is few, and rigidly connect suspension column with the crab-bolt formula and compare and can save steel about 15%, and simple structure, be convenient to make.
Description of drawings
The utility model is described in further detail below with reference to drawings and Examples.
Fig. 1 is that prior art crab-bolt formula rigidly connects the suspension column structural representation;
Fig. 2 is Fig. 1 sectional view;
Fig. 3 is that the utility model plug-in type rigidly connects the suspension column structural representation.
Among the figure: anchor bolt 1, base plate 2, base plate 2 ', stiffening rib 3, stiffening rib 3 ', steel column 4, steel column web 5, the steel column edge of a wing 6, backing plate 7, pea gravel concreten or high-strength grout 8, basis 9 ', basis 9, basic rim of a cup 10.
The specific embodiment
As shown in Figure 3, a kind of steel column plug-in type rigidly connects suspension column, comprises steel column 4, basic rim of a cup 10, in 9 centre, basis a basic rim of a cup 10 is arranged, basic rim of a cup 10 be shaped as the shape of falling truncated rectangular pyramids rim of a cup.Fixing by pouring nothing contraction pea gravel concreten or high-strength grout 8 between steel column 4 and the basic rim of a cup 10, there is a base plate 2 steel column 4 bottoms.Steel column 4 bottoms are equipped with base plate 2, and when steel column 4 liftings, pea gravel concreten under the base plate 2 or high-strength grout 8 be supporting steel column 4 better, is convenient to the adjustment and the correction of steel column 4.Be equipped with base plate 2 and help steel column 4 to the more uniform transmission pressure in basis, avoid stress too concentrated, base plate 2 thickness requirements are thinner, and steel using amount is less.Be positioned at basic rim of a cup 10 tops above the steel column 4 steel column web stiffening rib 3 is housed, steel column web stiffening rib 3 is 70～120mm apart from the distance of basic rim of a cup 10 end faces, and this example is 100mm.Be equipped with web stiffening rib 3, stable with the part that guarantees steel column web 5, for pouring and vibrate pea gravel concreten or high-strength grout 8 provide the operating space, being convenient to pea gravel concreten or high-strength grout 8 waters fully and makes when vibrating more closely knit, stiffening rib 3 thickness are thinner, so steel using amount is fewer.The steel column edge of a wing 6 is 30～100mm with the distance of basic rim of a cup 10 sides, and this example is 50～75mm.Base plate 2 on the steel column 4 is 30～70mm with the distance of basic rim of a cup 10 bottom surfaces, and this example is 50mm.The degree of depth that steel column 4 inserts basic rim of a cup 10 is not less than 1.5h, and wherein h is steel column 4 depth of sections.The degree of depth that steel column 4 inserts basic rim of a cup 10 is not less than 1/20 of steel column 4 length.
